There is no such thing as a 'passive Baxandall'; the circuit *depends*
on negative feedback.
If he is using the tonestack.exe program to choose tonecontrol circuit
he may have read this passus in the help file:
"The James control was described in Wireless World during February
1949, although it is claimed that Michael Volkoff first used this type
of control in July 1939. Many would describe it as a Baxandall
control, although the true Baxandall control was an adaptation of the
James control using negative feedback."
The tonestack.exe is a cute program which is fun to play with.
I think it can be found on the web with the search word tonestack.exe,
or maybe just tonestack.
It is describing and simulating different tone control circuits which
have been used in electric guitars and elsewhere.
